COMBINED THREAD CUTTER AND HOLDER.

SPECIFICATION forming part of Letters Patent No. 314,518, dated March 24, 1885.

Application filed February 2, 1884. No model) To all whom it may concern;

Be it known that I, JOHN L. O. CRONYN, a citizen of the United States, residing at Buffalo, in the county of Erieand State of New York, have invented certain new and useful Improvements in a Combined Thread Cutter and Holder; and I do hereby declare the following to be a full,'clear, and exact description of the invention, such as will enable oth ers skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to an improvement in that class of combined thread cutters andholders which are secured to the spools; and the object of my invention is to produce a combined thread cutter and holder which is simple in construction, and which has its cuttingedge arranged closely against the end of the spool ,whereby the cutting-edges are prevented from coming in contact with the hands of the person using the spool, while the projecting blunt end of the holder enables thethread to be easily caught and held.

My invention consists to that end of theiinprovements which will behereinafter fully described, and pointed out in the claim.

In the accompanying drawings, Figure 1 is a perspective viewof a spool of thread with to. Fig. 2 is an end view of the spool, illustrating the manner of holding the thread. Fig. 3 is a similar view illustrating the manner of cutting the thread. Fig. 4. is aperspective view of the cutter and holder detached from the spool. Fig. 5 is a cross-section in line 00 as, Fig. 4.

Like letters ofrei'erence refer to like parts in the several figures.

a, is a spool to which my improved cutter and holder is attached, and bis the thread wound upon the spool.

The cutter and holder, as clearly shown in Fig. 4, consists of the thin narrow portion 0 portion 0 has its sides sharpened, or formed with cutting-blades c, which preferably extend from a point near the shank d to or nearly to its other end. These blades are preferably formed by beveling or grinding away both the upper and lower surfaces of the strip 0, as shown in Fig. 5, although it is apparent that beveling one surface only would suffice. The cutter would operate with a blade on the in nor side alone; but by forming a blade on both sides of the strip 0 the device is adapted to be secured to either end of the spool. The holding-shank d is provided with a tapering end, d, for easy insertion into the end of the spool. The tapering portion preferably extends only part way up the shank, the remaining shouldered portion (l being left, as shown, to pre vent accidental turning of the device when it is driven into thespool. The end of the strip 0 opposite the shank d is made blunt and round ed, so as to completely protect the manipulator s hand.

The application of the device to the spool and its operation is as follows: The pointed shank d d is driven into the end of the spool in such a manner that the body portion 0 will assume a position, substantially as shown in the drawings, so that the cuttingedge 0 will form an acute angle with the tangent (shown in dotted lines in Fig. 3) drawn atthe point of intersection of the cutting-edge c with the outer periphery of the spool. This position enables the thread to be drawn against the blade at an acute angle, thus making the cutting action more effective. The outer blunt end is preferably located so that it projects slightly beyond the edge of the spool, thus forming a shoulder to catch the thread in the operation ofcutting the same. The blade portion 0 should rest against the end of the spool closely enough to hold the thread securely when not in use, as illustrated in Fig. 2, thus enabling the device to be equally well employed as a threadholder.

It will be seen that with my improved cutter and holder it is impossible to injure the hand of the person holding the spool; that the device does not interfere with the free use of the spool upon a sewing-machine, and takes up very little room when applied to the spool.

I am aware that athread-cutter has been applied to the edge or peripheral face of a spool, and this I do not claim, because in such construction the cuttingedge is exposed and lie ble to cut the hand of the person using the thread holder and cutter consisting of a point- I spool; also, that a cutter provided with a cut- I claim as my i11vention- The combination,'\vithaspool,of acoinbined I the cutting-edges are prevented from coming in contact with the hand, While the thread is easily caught and cut, substantially as set forth.

In testimony whereof Ihavesigned my name to this specificationin the presence of two subed shank, d, which is driven into the end of scribing witnesses.

the spool, and a flat arm, a, which extends I JOHN L. C. ORONYN. closely along the end of the spool and has its Sides sharpened and its bluntend projecting slightly beyond the edge of the spool, whereby WVi tnesses:
